TECHNICAL FIELD

The present invention relates to an N-phenylarylsulfonamide compound.

More detailed, the present invention relates to

(1) an N-phenylarylsulfonamide compound of formula (I)

wherein all symbols have the same meanings as defined hereinafter, (2) a prostaglandin E₂ receptor (EP₁) antagonist which comprises the compound as an active ingredient, (3) a compound of formula (II)

wherein all symbols have the same meanings as defined hereinafter, and (4) a process for its preparation.

BACKGROUND ART

Prostaglandin E₂ (abbreviated as PGE₂) has been known as a metabolite in the arachidonate cascade. It has also been known that PGE₂ possesses a cyto-protective activity, a uterine contractive activity, a pain-inducing effect, a promoting effect on digestive peristalsis, an awakening effect, a suppressive effect on gastric acid secretion, a hypotensive effect, a diuretic activity and so on.

In a recent study, it was found that a PGE₂ receptor is divided into some subtypes which possess different physical roles from each other. At present, four receptor subtypes are known and they are called EP₁, EP₂, EP₃ and EP₄ respectively (Negishi M. et al., J. Lipid Mediators Cell Signaling, 12, 379-391 (1995)).

PGE₂ possesses a variety of physiological activities, so the undesired action other than the aimed one is shown as side effect. The research for the role of each receptor subtype and the investigation of the compound which only shows the effect on the specific subtype have been carried out to overcome such a problem.

Among these subtypes, it has been known that EP₁ subtype relates to induction pain, pyrexia (induction fever) and diuresis (ref Br. J. Pharmacol., 112, 735-740 (1994); European J. Pharmacol., 152 273-279 (1988); Gen Pharmacol., September 1992, 23(5) 805-809). Therefore, compounds which antagonize this receptor are considered to be useful as analgesics, as antipyretic agents and as agents for treating pollakiuria (frequent urination).

It has also been known that EP₁ antagonists possess a suppressive effect on aberrantcryptfoci and formation of intestinal polyps, and that they indicate an effective anti-tumor activity (ref. WO00/69465).

After drugs are absorbed in the body, they mainly migrate into the bloodstream. Then they are transported in the blood and are delivered to target organs. Finally they exert their potency. However, some drugs do not exert their potency because they combine with some proteins, which is contained in blood as nutritive substances. While some compounds are effective in in vitro experiment, it may often turn out that they are not effective in in vivo experiment. And it has been well known that there is not a specific structure-activity relationship on binding between drugs and proteins, and that it is very difficult to find out the ordinality.

The present inventors found a useful compound which is an EP₁ antagonist, and filed a patent application. In the specification of WO98/27053 (EP947500), it is disclosed that a sulfonamide compound of formula (A)

wherein the group

are each independently C5-15 carbocyclic ring etc.; Z^(1A) is —COR¹ etc.; Z^(2A) is hydrogen etc.; R^(1A) is hydroxy etc.; Z^(3A) is single bond etc.; Z^(4A) is SO₂ etc.; Z^(5A) is 5 to 7 membered heterocyclic ring containing one or two oxygen, sulfur or nitrogen atom(s), which may be substituted with 1 to 5 R^(5A) etc.; R^(5A) (if two or more R^(5A), each independently) is hydrogen, C1-6 alkyl etc.; R^(2A) is Z^(7A)-C1-4 alkylene etc.; Z^(7A) is oxygen etc.; R^(3A) is trifluoromethyl etc.; R^(4A) is C1-8 alkyl etc.; n^(A) and t^(A) are each independently 1 to 4 (as excerpt), binds to a PGE₂ receptor, especially the EP₁ receptor, to show an agonistic or an antagonistic activity. The specification disclosed that the compound having the antagonistic activity is useful for the prevention of abortion, as an analgesic, as an antidiarrhoic, as a hypnagogic agent and for treating pollakiuria (frequent urination), while the one having an agonistic activity is useful for abortion, as an abstergent, as an antiulcer agent, as an antigastritis agent, as an antihypertensive agent, as a diuretic agent.

In this patent application, for example, the following compounds are disclosed specifically.

(1) Example 18(93)

(2) Example 18(113)

(3) Example 18(125)

(4) Example 18(121)

(7) Example 18(124)

(8) Example 18(94)

(9) Example 21(13)

(10) Example 21(14)

In the process of the researches about these compounds, it was revealed that these compounds have some problems that they are susceptible to the influence of protein binding and that they do not have a satisfactory in vivo activity.

Esters:

Among the compounds of formula (I) of the present invention, the compound of formula (I-B) may be converted into the corresponding ester by methods known per se. The conversion into ester is useful, because of increase of stability and absorbability of the compound. An alkyl ester is preferable. C1-4 alkyl ester is more preferable. The ester of formula (I-B) may be prepared by methods known per se. It may also be obtained as the compound of formula (I-A) in the process of preparing the compound in the present invention.

Salts:

The compound of formula (I) of the present invention may be converted into the corresponding salt by methods known per se. A non-toxic and water-soluble salt is preferable. A suitable salt, for example, includes a salt of alkali metals (potassium, sodium, etc.), a salt of alkaline earth metals (calcium, magnesium, etc.), an ammonium salt, a salt of pharmaceutically acceptable organic amines (tetramethylammonium, triethylamine, methylamine, dimethylamine, cyclopentylamine, benzylamine, phenethylamine, piperidine, monoethanolamine, diethanolamine, tris(hydroxymethyl)methylamine, lysine, arginine, N-methyl-D-glucamine, etc.).

Method for the Preparation of the Compound in the Present Invention:

The compound of formula (I) of the present invention may be prepared by methods described in WO98/27053, or according to the reaction schemes outlined below. Details of the process are described below.

In the schemes, R is C1-4 alkyl, Tf is trifluoromethanesulfonyl and the other symbols have the same meanings as defined hereinbefore.

R: C1-4 alkyl;

Ms: mesyl;

Tf₂O: trifluoromethanesulfonic acid anhydride;

Et: ethyl;

TCDI: 1,1′-thiocarbonyldiimidazole.

Among the compounds of formula (I), when Ar is a heterocyclic ring having a basic part, its corresponding sulfonyl halide (the compound of formula (VII)) described in the reaction scheme (A) is susceptible to heat, and it was found that it easily decomposed when it is left as it was (see Comparison Example 1).

Particularly, it is easily expected that a sulfonyl halide having a basic part such as a heterocyclic ring containing a nitrogen atom is easily decomposed, since sulfonyl halide compounds are generally unstable to bases.

From these, in preparing a sulfonyl halide having a basic part, it was concerned that (1) it is hard to isolate a sulfonyl halide because the concentrated sulfonyl halide is unstable after evaporation of the solvent after the reaction terminated, and that (2) it was probable that the sulfonyl halide might decompose in the process of preparing a sulfonamide from it, when subjected to temperature higher than ambient temperature for a long time.

As described above, when the sulfonyl halide easily decomposes, it is difficult to determine the actual quantity of the sulfonyl halide, and it is cumbersome to treat it. When the sulfonamide compound is prepared by subjecting to condensation reaction with an amine compound, low yield is concerned due to the decomposition of the sulfonyl halide in the industrial mass production.

As to the method for the preparation of a sulfonamide, condensation reaction with a sulfonyl halide and an amine is generally known.

They disclose a method for transforming a phenylsulfonyl chloride into a sulfonamide or a sulfonic acid ester via an addition of an imidazole to a phenylsulfonyl chloride followed by N-methylation (J. Org. Chem., 57, 4775-4777 (1992)), and it is described that the method is useful in the case of reaction with a nucleophile having low nucleophilicity or sterically hindered one. However, it is not described nor suggested that the methods improve the stability of the sulfonyl halide.

The present inventors have investigated to convert a sulfonyl halide having a heterocyclic ring of formula (III) to a more stable compound to find that the purpose was accomplished by converting it to the compounds of formulae (II-A) and (II-B) according to the method for the preparation as shown in the following reaction scheme (C).

In the reaction scheme (C), step (a) is a method of converting to a stable sulfonyl compound with 1-hydroxybenzotriazole. For example, it is carried out with 1-hydroxybenzotriazole, in an organic solvent (an ether (t-butyl methyl ether, diethyl ether, tetrahydrofuran, etc.), a halogen solvent (methylene chloride, chloroform, etc.), etc.) in the presence of a base (triethylamine, diisopropylethylamine, dimethylaminopyridine, pyridine, etc.), at temperature of −20 to 30° C.

The step (b) is also a method for preparing a stable sulfonyl compound; for example, it is carried out in an organic solvent (an ether (t-butyl methyl ether, diethyl ether, tetrahydrofuran, etc.), a halogen solvent (methylene chloride, chloroform, etc.), etc.) with N-methylimidazole at temperature of −20 to 30° C.

The steps (a) and (b) are preferably carried out under an anhydrous condition under the atmosphere of inert gas.

Particularly, when the compound of formula (III) is unstable to heat, the each step (a) and (b) may be carried out without concentrating the prepared sulfonyl halide solution.

Sulfonyl halide of formula (III) is obtained as a solution after preparation, and generally it can be isolated by concentration of the solution. If the materials are exposed to high temperature while concentrating, there is a possibility that a sulfonyl halide may decompose by heating in a large scale, while there is no problem in particular in a small scale (see Comparison Example). Therefore, the transforming into the compound of formulae (II-A) or (II-B) without concentration of solution ensures a low degradability of a sulfonyl chloride with its high reactivity (see Examples 7 and 8).

In the reaction scheme, the sulfonyl halide of formula (III) used as a starting material is known in itself or may be prepared easily in a conventional method from a known compound. The other starting materials and reagents in the present invention are known in themselves or may be prepared according to conventional methods.

Pharmacological Activity of the Compounds of the Present Invention:

The compound of formula (I) of the present invention can bind strongly to the EP₁ receptor which is a subtype of prostaglandin E₂ receptor and shows an antagonistic activity. As mentioned hereinbefore, it is known that the EP₁ receptor relates to induction pain, pyrexia (induction fever), diuresis or bladder contractive activity. The compound of formula (I), an ester thereof and a non-toxic salt thereof, which can antagonize this receptor, are therefore useful as analgesics, as antipyretic agents or as agents for the prevention and/or treatment of pollakiuria (neurogenic bladder, nervous bladder, stimulated bladder (irritable bladder), detrusor instability, dysuria accompany prostatomegaly), acraturesis (urinary incontinence), lower urinary tract disease syndrome. In addition, the compound of the present invention scarcely binds to the other subtypes of PGE₂ and is expected to provide an agent with no side effect.

It has also been known that an EP₁ antagonist possesses a suppressive effect on aberrantcryptfoci and formation of intestinal polyps, accordingly it indicates an effective anti-tumor activity.

The experiment described below shows evidently that the compound of the present invention is less affected by protein binding, so it has a satisfactory in vivo activity.

Pharmacological Experimental Test

(i) Binding Assay Using Expression Cell of Prostanoid Receptor Subtype

The preparation of membrane fraction was carried out according to the method of Sugimoto et al. (J. Biol. Chem., 267, 6463-6466 (1992)), using expression CHO cell of prostanoid receptor subtype (mouse EP₁, EP₂, EP_(3α) or EP₄).

The standard assay mixture containing membrane fraction (0.5 mg/ml) and ³H-PGE₂ in a final volume of 200 μl was incubated for 1 hour at room temperature. The reaction was terminated by addition of ice-cold buffer (3 ml). The mixture was rapidly filtered through a glass filter (GF/B). The radioactivity associated with the filter was measured by liquid scintillation counting.

K_(d) and B_(max) values were determined from Scatchard plots (Ann. N.Y. Acad. Sci., 51, 660 (1949)). Non-specific binding was calculated as the binding in the presence of an excess (2.5 μM) of unlabeled PGE₂. In the experiment for competition of specific ³H-PGE₂ binding by the compound of the present invention, ³H-PGE₂ (2.5 nM) and the compound of the present invention were added. The following buffer was used in all reaction.

Buffer: potassium phosphate (pH 6.0, 10 mM), EDTA (1 mM), MgCl₂ (10 mM) and NaCl (0.1 M).

The dissociation constant K_(i) (μM) of each compound was calculated by the following equation. Ki=IC ₅₀/(1+([C]/Kd))

wherein [C] is concentration of ³H-PGE₂ used in the reaction

The results are shown in Table 1.

(ii) Experimental Measurement of the Activity of Receptor Antagonism Using Cells Expressing Prostanoid Receptor Subtype EP₁ in the Presence of BSA (Bovine Serum Albumin)

The cells expressing mouse EP₁ receptor were seeded at 1×10⁴ cells/well in 96 well plates and cultured for 2 days with 10% FBS (fetal bovine serum)/minimum essential medium Eagle alpha modification (αMEM) in the incubator (37° C., 5% CO₂). The cells in each well were rinsed with phosphate buffer (PBS(−)), and load buffer was added. After incubation for 1 hour, the load buffer was discarded. After the addition of the assay buffer to each well, the cells were incubated in a dark place at room temperature for 1 hour. After the addition of a compound of the present invention (10 μl) and PGE₂ (10 μl) which were prepared with assay buffer, intracellular calcium concentration was measured with Fluorescence drug screening system (FDSS-4000, Hamamatsu Photonics). A pair of fluorescence intensities emitted 500 nm by an excitation wavelength of each 340 nm and 380 nm was measured.

The EP₁ antagonist activity was estimated as percent inhibition of the increase of intracellular calcium concentration induced by PGE₂ (100 nM).

Load buffer: 10% FBS/αMEM containing 5 μM of Fura 2/AM, 20 μM of indomethacin, 2.5 mM of probenecid

In the experiment coexistent with proteins (measurement of activity of signaling in cells), the compound of formula (I) of the present invention indicated ten fold as high activity of inhibition of signaling as the compound specifically described in WO98/27053 or more.

It shows that the compound specifically described in WO98/27053 is affected by protein binding to descend its activity in coexistence with serum protein.

(iii) Experiment to Assess the Inhibition of Sulprostone-Induced Increase of Intravesical Pressure of Bladder in Rats.

Female rats (Wistar) were anesthetized by urethane and their both ureters were ligated and cut off at the kidney side. The urinary bladder was incised its top and catheter was inserted. The other end of catheter was connected to the pressure transducer and the infusion pump. Repeated micturition reflex, which was induced by the continuous infusion of citrate buffer (pH 3.5) into the bladder, was recorded. The increase of micturition pressure was elicited by the subcutaneous injection of diclofenac (5 mg/kg) and sulprostone (300 μg/kg). Since such an increasing effect was not observed by the treatment of EP₃ agonist, it was considered that this increase was caused by the activation of EP₁ receptor. The inhibitory effects of the compound of the present invention on this increase of intravesical pressure were measured for 60 minutes after the intraduodenal administration (2 ml/kg).

Table 3 shows the percent inhibition of increase of intravesical pressure at 40 minutes after the administration (1 mg/kg).

(iv) Experiment to Assess the Antagonistic Activity on the Increase in Urination Volume and Number Induced by Sulprostone to Rats.

Male rats (CD (SD) IGS) were used and micturition number and urination volume were measured by means of a Micturition volume measurement system (Neuroscience).

A compound of the present invention was orally administrated (4 ml/kg), and 30 minutes later, sulprostone (200 μg/4 ml/kg) was subcutaneously administered. Number and volume of urination were continuously monitored for 3 hours from the administration of sulprostone.

The percent inhibition of each compound was calculated by the following equation.

${{Inhibition}\mspace{14mu}(\%)} = {\frac{\begin{matrix} {\left( \begin{matrix} {{number}\mspace{14mu}{of}\mspace{14mu}{micturitio}} \\ {\;{{in}\mspace{14mu}{control}\mspace{14mu}{group}}} \end{matrix}\mspace{11mu} \right) -} \\ \left( \begin{matrix} \begin{matrix} {{number}\mspace{14mu}{of}\mspace{14mu}{micturition}\mspace{14mu}{in}} \\ {\;{{test}\mspace{14mu}{compound}\mspace{14mu}{in}\mspace{14mu}{the}}\mspace{14mu}} \end{matrix} \\ {{present}\mspace{14mu}{invention}\mspace{14mu}{group}} \end{matrix}\mspace{11mu} \right) \end{matrix}}{\left( {{number}\mspace{14mu}{of}\mspace{14mu}{micturition}\mspace{14mu}{in}\mspace{14mu}{control}\mspace{14mu}{group}} \right)} \times 100}$ Comments:
